PHONOGRAPH RECORD.

Application filed October 26, 1921.

T @ZZ whom t may concern.'

Be it known that I, JOHN J. Rsrnrionn,

a citizen of the United States, and aresident of lfiarietta, county ofLancaster, State 0f Pennsylvania, have invented certain new and usefulimprovements in Phonograph Records, of which the following is aspecification.

yfhis invention relates to phonograph recm ords of the disk type.

It is a difficult matter to pick up disk records from a fiat surface,such as the turntable of talking-machines, especially, when they arevery thin and have an edge of the usual shape.

When a number of records are stacked one on top of the other it isusually necessary when picking one oil", to slide it partially oft' thestack before a firm hold can be obtained upon the same; this is theusual habit when picking a record off the stack because it seems to bethe most convenient way; the object-ion to this is that some of therecords become scratched and the sound grooves become worn away by thissliding action.

The object of this invention is to provide means whereby the abovestated diiiiculties and objections are eliminated.

ln carrying out this invention l construct the edge or periphery of thedisk of a shape which is adaptable to engage with the finger nails ofthe human hand, through which the disk can be readily lifted and thefingers placed under the same to enable a person to get a firm hold. Thehandling of records is greatly facilitated when formed as herein shownand described.

This invention will be more fully understood from the followingdescription, when taken in connection with the accompanving drawing,forming a part hereof, and in which similar numerals refer to similarparts throughout the several views.

Referring to the drawing:

Fig. l, is a sectional view of a turn table of the type usually employedwith talking machines, upon which is carried a record of the commontype.

Fig. 2, is an enlarged sectional view of a portion of the turn tableshown in Fig. l,

Serial No. 510,616.

and a portion of a record showing the principal features of thisinvention.

Fig. 3, shows a modification of my improved record as shown in Fig. 2.

l, represents the top board of the ordinary talking machine. 5, is theturn table supported on the end of the vertical shaft 6; both of whichare caused to rotate in the usual manner.

7. is a disk record of the common type which is carried by the turntable 5 and is centered on the pin 8. 9 and 10 represent a portion ofthe fingers of a human hand, and in position as when endeavoring to liftthe disk record 7 from the turn table 5.

l here point out the diculties encountered in endeavoring to lift therecord from the turn table, in that it will readily be 0bserved, and iswell known to be a fact, that 1n practice the disk record 7 is so thinthat it is a tedious matter to obtain a firm hold to lift the same;because it is impossible to get under it with the finger nails. Theresults of such endeavors are generally that the record slips from thefingers before a firm hold can be obtained upon the same, this is veryannoying, and further the records often break as a result of the fallcaused thereby.

l facilitate the lifting of the records from the turn table by forming afurrow or groove in the periphery of the disk record 7 as shown at l1.The shape of this furrow must be such so that the linger nails can beengaged therein and the record raised sufciently to get the fingersunderneath and get Iirm hold thereon.

At l2, Fig. 3, I show a modification of the furrow shown at 11 in Fig.2. I prefer the shape of furrow shown at ll over that shown at 12, forthe reason that it better accommodates the engagement of the fingernails. lt has a disadvantage howeventhat it produces a very thin flangeas indicated at 13, which is easily broken; and for this reason thefurrow shown at l2 may be considered by many as being of the bettertype. The flanges indicated at 14 are heavier and will not be so easilybroken. It is obvious however, that a medium might be found between thefurrow shown at ll and the one shown at 12 without departing frorn the`nature and scope of this invention as set forth in the claim, and whichmay be considered as having the most advantages.

t of course should be understood that sound producing grooves vmay beplaced on one or bothsdes of the disk 7; the furrows 11 and 12 beingsuchso that they will give the desired results regardless of which sideture. l@ of the disk 7 is laid against the turn table.

Having thus described my invention, what I claim and desire to secure byUnited States Letters Patent is as follows:

A one piece disk shaped phonographreeV Vhuman linger nails.
